Abstract

A method and apparatus for automatically filling and sealing envelopes in a complete sequence starting with envelopes being placed in an initial position and terminating with filled envelopes being delivered fully prepared for being labelled and stamped. The novel feature is turning the envelopes from a position with their front sides facing downwards into a position with their reverse sides facing downwards, with the contents of the envelopes being introduced when they are in the last-mentioned position. In consequence of the invention a faster operating and considerably more compact apparatus can be attained than in the prior art.

Description

515_654 2 Kuverteringsmaskinen enligt uppfinningen kommer att beskrivas i detalj med hänvisning till bifogade figurer, varvid fig. l visar en maskin enligt uppfinningen i förenklad form med endast de väsentliga delarna åskádliggjorda och fig. 2 visar mitt- partiet av fig. l i större skala. The enveloping machine according to the invention will be described in detail with reference to the accompanying figures, Fig. 1 showing a machine according to the invention in simplified form with only the essential parts illustrated and Fig. 2 showing the middle portion of Fig. 1 on a larger scale.

I figur l avser beteckning l en kuvertstapel som ligger på ett eller flera inbördes parallella matarband 2. Ett bakre kuvertstöd 3 kan med fördel finnas så att kuverten skall få en jämn anliggning mot matarbanden 2. Kuvertstödet 3 kan fixeras i läge medelst en låsning 3'.In Figure 1, designation 1 refers to an envelope stack lying on one or more mutually parallel conveyor belts 2. A rear envelope support 3 can advantageously be present so that the envelopes have an even abutment against the conveyor belts 2. The envelope support 3 can be fixed in position by means of a locking 3 ' .

En separationsanordning bestående av ett främre kuvertstöd innefattande en.medelst en omställningsmekanism 4a ställbar separa- tionsrulle 4b finns vid slutet av matarbandet 2 i dennas matnings- riktning som är markerad med en pil 2'. I drift avskiljs det under- sta kuvertet från kuvertstapeln och kan matas ut från kuvertstapeln genom separationsanordningen. Gapet mellan.separationsrullen.4b och matarbandets främre matarvals 5 är precis lagom för att ett enda kuvert skall kunna föras igenom. I läget 1 ligger kuvertet med fliken hopvikt och vänd uppåt vid la.A separation device consisting of a front envelope support comprising a separating roller 4b which can be adjusted by means of an adjustment mechanism 4a is located at the end of the conveyor belt 2 in its feeding direction which is marked with an arrow 2 '. In operation, the lower envelope is separated from the envelope stack and can be ejected from the envelope stack through the separation device. The gap between the separation roller 4b and the front feed roller 5 of the conveyor belt is just right for a single envelope to be passed through. In position 1, the envelope with the flap is folded and turned upwards at 1a.

Sedan kuvertet har börjat gå igenom gapet mellan separationsrullen 4b och matarvalsen 5 matas det av matarbandet 2 så att det med sin främre ände kommer in mellan en första positioneringsvals 6 och en medelst en kraft F påverkad ryttarrulle 7. Positioneringsvalsen 6 är motordriven och drar fram kuvertet till en klaff eller fliköppnare 8 som styr kuvertet vidare mot en positioneringsvals 6'. När kuvertets framkant har passerat klaffen 8 trycks denna ned till läget 8' och viker upp kuvertets flik.After the envelope has started to pass through the gap between the separation roller 4b and the feed roller 5, it is fed by the feed belt 2 so that it enters with its front end between a first positioning roller 6 and a rider roller 7 actuated by a force F. The positioning roller 6 is motor driven and pulls the envelope to a flap or flap opener 8 which guides the envelope further towards a positioning roller 6 '. When the front edge of the envelope has passed the flap 8, it is pressed down to the position 8 'and unfolds the flap of the envelope.

Kuvertet matas vidare kring positioneringsvalsen 6' där det hålls mellan en ryttare 10 och positioneringsvalsen 6'. Kuvertets stoppläge beräknas genom att kuvertflikens fals passerar en givare ll'. Sedan falsen har passerat givaren ll' fortsätter kuvertet sin rörelse en bestämd sträcka och stannar därefter. Detta medför att man inte behöver ställa in maskinen för olika format.The envelope is further fed around the positioning roller 6 'where it is held between a rider 10 and the positioning roller 6'. The stop position of the envelope is calculated by the fold of the envelope flap passing a sensor ll '. After the fold has passed the sensor ll ', the envelope continues its movement for a certain distance and then stops. This means that you do not have to set the machine for different formats.

En sensor ll har till uppgift dels att kontrollera att ett kuvert passerar, dels att kontrollera att kuvertfliken är utfälld.A sensor 11's task is partly to check that an envelope passes, and partly to check that the envelope flap is unfolded.

I fig. l och 2 betecknar 24 ett pappersstopp för att hindra att papper som skall matas in i ett kuvert glider in i detta okontrollerat. Papper som skall införas i kuvert matas in på en 515 654 3 bana 27 och upp på en styrning 25 och därefter på en styrning 26 in i kuvertet. Styrningarna 25 och 26 medför att inmatningsanord- ningen blir självjusterande, varigenom man blir oberoende av kuvertformat, kuverttyp och antal dokument.In Figs. 1 and 2, 24 denotes a paper jam to prevent paper to be fed into an envelope from sliding into it unchecked. Paper to be loaded into envelopes is fed onto a web 27 and up onto a guide 25 and then onto a guide 26 into the envelope. The guides 25 and 26 mean that the input device becomes self-adjusting, whereby one becomes independent of the envelope format, envelope type and number of documents.

Verktyget V och rörelsen hos komponenterna 24, 25 och 26 styrs av en excenterskiva 28 med tillhörande vevstake 29.The tool V and the movement of the components 24, 25 and 26 are controlled by an eccentric disc 28 with associated connecting rod 29.

Kuvertets öppning eller buk är nu öppen nedåt så att doku- menten kan föras in underifrån. Ett medbringarband 12 matar in dokumenten, t.ex. ett blankettset, i kuvertet. Medbringarbandet 12 synkroniseras med positioneringsvalsarna. 6 och 6' 12' och släpper kuvertet då medbringaren befinner sig vid falsvecket.The opening or belly of the envelope is now open downwards so that the documents can be inserted from below. A carrier tape 12 feeds the documents, e.g. a set of forms, in the envelope. The carrier belt 12 is synchronized with the positioning rollers. 6 and 6 '12' and releases the envelope when the carrier is at the fold.

Medbringarbandet 12 fortsätter' att föra. kuvertet fram till en förslutningsstation 14. Två sensorer 15 och 16 ligger längs medbringarbandet 12, varvid sensorn 15 känner av att det finns kuvert och sensorn 16 igångsätter förslutningssekvensen.The carrier belt 12 continues to carry. the envelope up to a sealing station 14. Two sensors 15 and 16 lie along the carrier belt 12, the sensor 15 sensing that there are envelopes and the sensor 16 initiating the sealing sequence.

Kuvertet transporteras framåt mellan valsar 21 tills en befuktningsvals 18 har passerats, varefter kuvertet stannar. Där- efter backas kuvertet och en flikgejd 19 fälls ned till ett läge 19' och styr ned fliken i en flikficka 20. Därefter höjs gejden 19 och backas kuvertflikens falsveck mellan förslutningsvalsarna 21, varvid limämnet på fliken pressas mot befuktningsvalsen 18 och kuvertet försluts då fliken kommer in mellan valsarna 21.The envelope is transported forward between rollers 21 until a humidifying roller 18 has been passed, after which the envelope stops. Then the envelope is backed and a flap guide 19 is folded down to a position 19 'and guides the flap down into a flap pocket 20. Then the guide 19 is raised and the envelope fold of the envelope flap is backed between the closing rollers 21, whereby the adhesive on the flap is pressed against the humidifying roller 18. enters between the rollers 21.

I fig. 1 avser beteckningen 23 en display och knappsats för operatörskommunikation.In Fig. 1, the designation 23 refers to a display and keypad for operator communication.

Uppfinningen är inte begränsad till den ovan beskrivna och på ritningarna visade utföringsformen, utan denna utgör endast ett exempel på uppfinningen och dess tillämpning.The invention is not limited to the embodiment described above and shown in the drawings, but this is only an example of the invention and its application.
